[amsat-bb] 18 el cp yagi

[Bob- W7LRD]

Hello 

I am refurbishing a 18 element CP yagi.  I am not sure of the manufacturer.  I opened up the relay switching box and found a lot of moisture (Yes I live near Seattle) in the box.  Lots of yuck and rust, on non stainless steel hardware..  The 12V connector is a simple phono plug, which should never be used outside.  Before I reinvent the wheel has anyone been here before?  Replace the phono plug, sealing everything.  In the past I have used a material called 3M5200, a marine sealant, nasty but almost permanent.  Suggestions please.
